AGAIN: [linux-lvm] Kernel 2.4 -- invalid i/o protocol version

Hi guys, I'm posting this again, if anyone has any idea, please let me know, I
need make lvm work.
Thanks
I'm having some trouble trying to make LVM work.
I've recently installed a new server, runing RedHat 7.0. I have also
installed 2.4 kernel with LM support.
Then I have downloaded lvm-0.8final from the sistina ftp site, then I
compiled it (I also included the patch) and I installed it. (well, no eveything
was so smoothly, but it's installed now).
I can load the lvm-module fine, but when I run vgscan or pvcreate (I
also created a 0x8e type partition in my primary scsi disk) it complains saying
that: "vgscan -- invalid i/o protocol version"
Do you have any ideas how to fix it?
I only have one scsi disk of 18GB, but I will add at least another 2 in the
next month, so I need it working. Do you think this will work?? I'm almost
betting my job on it.
thanks
